Philips Avent Natural Teat for thick liquids helps bottle-feed more naturally for you and your baby. The teat has an innovative design with petals that allows a natural latching similar to that of the breast, making it easy for the baby to combine feeding with the breast and bottle. The wide shape of the teat allows for a natural, breast-like support and makes it easier for your baby to breastfeed and bottle feed. The petals inside the teat increase softness and flexibility without shrinking the teat. The baby will enjoy a more comfortable and pleasant feeding. The innovative dual valve design reduces colic and discomfort by venting air into the bottle and not into the baby's tummy. This teat is made of silicone, a BPA-free material (according to the EU directive, 2011/8 / EU) Philips Avent offers four different flow levels to keep up with your baby's growth. Remember that age indications are approximate, as babies grow at different rates. Philips Avent offers the 1-hole (0m +) newborn flow teat, the 2-hole slow-flow teat (1m +), the 3-hole medium-flow teat (3m +) and the fast-flow nipple with 4 holes (6m +). All teats are available in double packages. It is recommended to use with thick liquids in children from 6 months.
